概要

• 論文の詳細を見る

• We have performed 2.5-dimensional general relativistic magnetohydrodynamic (MHD) simulations of collapsars as a model of gamma ray bursts (GRBs). This simulation showed the formation of a disk-like structure and the generation of a mildly relativistic jet (〜0.3c). We have found the jet is accelerated by the magnetic pressure and the centrifugal force and is collimated by the pinching force of the toroidal magnetic field amplified by the rotation.
